How to calculate a grade out of 23
Percent = score ÷ 23 × 100
For example, 18 out of 23 is 18 ÷ 23 = 0.7826, × 100 = 78.26%, a C+. Every question you miss costs 4.35 percentage points, so the gap between letters is often a single question.
Letters follow the standard U.S. plus/minus grading scale. If your teacher uses different cutoffs (like 93/85/77/70), build a custom chart with the EZ Grader. For a single score, the test grade calculator is quickest.
